11th PAMIR International Conference- Fundamental and Applied MHD July 1-5, 2019, Reims, EVEM France

The present work shows the experimental realisation of three-dimensional magnetoconvection studies at Rayleigh numbers between 10e6 and 6 · 10e7 and Hartmann numbers up to 1000 in a Rayleigh-Bénard convection cell. The fluid in the cell is the GaInSn metal alloy with a low Prandtl number of 0.029. The flow is investigated using thermocouples and ultrasound-Doppler-velocimetry. The change of the Nusselt number with increasing Hartmann number is studied and presented. Experimental results are compared to other experiments and simulations.
